Mission, Vision & Philosophy

Welcome to Cornerstone at Pedregal!


As a parent participation school, we come together with a common focus on the “whole child” with a strong academic foundation dedicated to the social emotional well-being of all students. Families, community, and staff partner to provide an outstanding school experience for our students.


We are an established leader in academic excellence with our innovative participation model that is nationally recognized. A California Distinguished School in 2004 and 2010, Cornerstone had the honor of becoming a California Gold Ribbon School in 2016. In addition, Cornerstone was honored with the 21st Century Schools of Distinction award.


Our school-wide focus on Growth Mindset and our newly transformed Character Counts program contribute to the message we hold near and dear to our hearts-- Cornerstone Cougars are able to learn and achieve whatever they set their minds to and we are here to support them. 


Cornerstone teachers are a dedicated and committed staff who care deeply for their students and their Cornerstone family.  You will see them often participating as teacher leaders in district professional learning opportunities. They remain grounded in educational pedagogy and are constantly growing, refining their teaching practices, and seeking innovative ways to engage all students.


Since 1993, our parents and staff have worked in partnerships to create a dynamic and responsive environment. A sense of extended family grows quickly here on campus with both children and parents supported by the in-service trainings provided by the child’s teacher throughout the year, multiple parent meetings, and opportunities to connect through guest speakers and specialized events.


We take pride in the many programs and spaces we have worked so hard to build with our parents and community partners. Our state-of-the-art Library and Learning Technology Center (LTC) are only some of the wonderful spaces our students are able to thrive. Classrooms utilize technology as a tool for enhancing instruction, and our science program is supported by parent volunteers. Students engage in hands-on experiments including STEM opportunities in our fully-equipped science lab.


What sets Cornerstone at Pedregal Elementary School apart is the opportunity we  provide for parents to be actively involved on a regular basis in their child’s educational journey. Our dedicated parents support the art, drama, music and other parent-led activities to complement District programs.


Here, at Cornerstone, we work together with teachers, staff and parents in the best interest of the whole child to prepare our students for wherever their learning path takes them.


Come visit us at Cornerstone! We are excited to welcome you!

Mission Statement
Cornerstone is a public elementary school that provides the unique opportunity for parents and staff to work together in partnership, offers an exceptional academic, cultural, and experiential environment for all students, and where:
  • teachers utilize the support of parents to deliver and enhance curriculum in a variety of creative ways
  • trained parents assist the teachers in the classroom on a regular basis, and while in that capacity develop a much greater sense of the educational needs of the children
  • students are provided the highest level of educational standards by talented teachers and are enriched with unique activities provided by resourceful and hard-working parents in fun, creative ways that encourage a love of learning
  • Everyone commits to these roles as part of a strong sense of extended family and community.
Vision Statement
Cornerstone School is an exemplary, cooperative, community of staff, administration, parents and students. As collaborative partners striving to go beyond standards and address the needs of the whole child, teachers utilize trained parents meaningfully and parents commit to support those teachers effectively. A sense of community abounds on campus with numerous extra-curricular activities driven by resourceful and creative parents, encouraged and supported by administration, and loved by students. This exceptional academic, social and cultural experience contributes to the development of responsible, confident and well-rounded students prepared for the opportunities and challenges of the future.

We commit to the education of the whole child; physical, emotional, intellectual, and social. We believe in helping each child to be challenged with the excitement of discovery. At Cornerstone, every day holds an exciting new experience, and school activities are looked upon as a part of life.

We commit to the stimulation of each child's natural curiosity and the joy of learning. Children are born learners, and given the proper environment and tools, they will continue to learn all their lives.

We commit to the nurturing of each child's positive self-image, personal self-discipline and respect, in an atmosphere of trust. Equally as important as the academics is the confidence and self-esteem that each child develops. Children learn best when they feel good about themselves and when they are taught in a supportive environment.

We commit to the development of each child's critical and creative thinking processes for problem solving, conflict resolution, self-discipline and interpersonal communication.

We commit to education as an extension of the family and will encourage active family participation in our children's learning experience as well as the school. The Administration and Teaching Staff are committed to working with the families in this kind of learning environment.

We are a community that cares about our environment. We embrace green progress by teaching and modeling environmentally responsible behavior.

It is our hope that our children will become whole beings, capable of giving to this world more than they take, sharing who they are, aware of the choices they have to make, capable of making those choices, and will be secure enough to live with their choices while sharing in the creation of the future.
